【Abstract】 By means of analysis on the weldability of weather resistant steel,we completed the low temperature anti-cracking test, the mechanics properties test of welded joint and the processing property between weather resistant steel and dissimilar steel, and analyzed micro-structure of welded joints. The welding procedure and materials suited for the welding of the high strength weather resistant steel were confirmed by tests.更多还原
